Publisher's Synopsis
What are UFOs--are they military aircraft, tricks of the light, or are they alien spacecrafts visiting Earth? For hundreds of years, people have been trying to make sense of many UFO sightings. This book discusses that exploration with a combination of logical scientific explanation and the sense of wonderment that anyone would feel when seeing something unexplained appear in the sky. The narrative travels back to the earliest sightings and explores some current mysteries as well.
